Use the crontab script you had before, adding the options listed by Mr. Gunthorpe. That solves the "staying up 'till midnight" problem. You can use another cron job to automatically kill the connection at 6am (with poff). You might have to do it again the next night if not everything was retrieved in one night.

When you run pon, it creates a file somewhere under /var that contains the process id of ppp. IIRC, it is /var/run/ppp.pid When you run poff, it looks in this file to see which process should be killed. You can probably find the name & location of this file with "man pon" if it isn't /var/run/ppp.pid. (It might be ppp0.pid) You could also just look in /var/run when you are connected. You could write a little script that checks if this file is still there. If it isn't, the script could restart the connection and apt-get, which will be smart enough to pick up where it left off. You can run this script with cron as well. A first stab at it could be: while true; do sleep 1200 test -f /var/run/ppp.pid || <your-apt-get-script> done This will (or at least, it should!) run <your-apt-get-script> if the file /var/run/ppp.pid doesn't exist. To avoid it reconnecting after 6am, you might add a simple counter so that it only executes 18 times. (18 since you want to be connected for 6 hours, and this sleeps for 20 minutes (1200 seconds) -- if it runs 18 times, it has run for 6 hours.) Kirk
